In normal operation, any 4 different operating variables
can be indicated continuously: 1.1 and 1.2 and
1.3 and 2. The present operating status or alarms
and warnings that have arisen are shown in line 2
in the form of a number. In the case of alarms, the
alarm in question will be shown in lines 3 and 4,
accompanied by an explanatory note. Warnings will
flash in line 2, with an explanatory note in line 1. In
addition, the display shows the active Setup.
The arrow indicates the direction of rotation; here the
VLT AFD has an active reversing signal. The arrow
body disappears if a stop command is given or if the
output frequency falls below 0.01 Hz. The bottom line
gives the status of the VLT AFD. See next page.
The scroll list on the next page gives the operating
data that can be shown for variable 2 in display mode.
Changes are made via the [+/-] keys.
